HT1329 Playlist transfer to new computer

Question

I've moved all the songs to my new computer.   To save time reorganizing, can all the playlists be moved also?

Answer 1

The playlists are stored in the iTunes library database file.  To preserve your complete iTunes library, including things like playlists, ratings, playcount, etc., what you need to do is move the entire iTunes folder, from your user account home folder to the new computer.  This includes your iTunes Media folder with your song files.
If you have already manually added the song files to a new iTunes library on the new computer (which creates a new iTunes library database file), you are beyond the point where you can easily get your old playlists back.
If you still have access to your old computer with its iTunes setup intact, you can follow this procedure to move your complete iTunes folder to the new computer. Then, iTunes on the new computer will look exactly like iTunes on the old computer.

The procedure to move the complete iTunes folder is the one called External drive. 
Although the procedure has many parts and steps, some of them may not apply to your situation.  At the high level, you are (1) consolidating your iTunes files so that they are all located in the iTunes folder.  If you have been using the standard settings for iTunes, all of your iTunes files may already be in the iTunes folder. Then, (2) copying that iTunes folder to an external drive.  And (3) copying that iTunes folder from the external drive to the new computer, to take the place of the existing iTunes folder.  If you know how to set up a network connection between the two computers, you can transfer the folder over that connection directly from one computer to the other (with no external drive needed). 
The next time you run iTunes on the new computer, it will use your old iTunes foider and it will look like iTunes running on your old computer, with all of your songs and playlists.
